Repair a bad weld

Jody, Could you do a video on how to grind out a bad weld and run a new weld? When you should and shouldnt, how bad is ok. I primarily do tig and mig mild steel. There are plenty of videos showing how to do thing right but what about when you mess up. I think it's a part of the learning process that...

Re: Tig overhead steel

I put some pictures attached you can see some of the hole that blew notice they aren't near my weld. And this isn't half of it I've already probably filled 20 or so holes. My original welds were pretty trashy it's about impossible to keep your tungsten clean as the zinc is constantly popping on you.

Re: Tig overhead steel

Now that I know what I'm up against I kind of understand my problem. It's not welding overhead at all it's this metal. After reading about welding electro galvanized metal I did what was suggested I cleaned everything front and back to bare metal and beyond at least 3 inches back. Started today with...

GTAW should only be used if al ...

Re: Tig overhead steel

Let's see I'm using 1/16 Er70S6 rod. Amps I can't tell you I'm using just my footpedal but my machine goes to 165 amps. I'm running a #5 cup on a 3/32 red tipped tungsten and the metal thickness carts from prob 16 gauge up to maybe 1/8 or more (some pinch welds have several layers of sheetmetal) the...

Re: Tig overhead steel

So my next idea I just to make a copper heat sink out of some pipe. I'll Cleco it to the back of the thin car metal that I'm trying to weld to my 2x3 box tube subframe connector. I can't tell you how many holes I filled this weekend.

Re: Tig overhead steel

Well I welded the topside of this subframe connector and had some problems with it as well. As it turns out in the 80's (my car is an 88 Trans AM GTA) that they electogalvanized with zink. I found this post online about it https://www.hobartbrothers.com/index.php?mact=News,cntnt01,print,0&cntnt0...

Re: Tig overhead steel

I did pretty good today. I cleaned everything up again. Turned my helmet down to 10 switched to a #5 cup from a #4 brought up my argon from 12 to 15. I did manage to blow a hole. Started to fill it up and instantly discovered why they sell leather welding jackets. Got burned not too bad but enough. ...

Tig overhead steel

I'm a pretty good tig welder but I need some help. I'm welding in some subframe connectors on my firebird and most of the welding is overhead. What are some of the tricks to keep the puddle from falling?
